Yamaha DGX-670: Do you love me?

Posted on by

Yes, I played one! The pandemic has let up to the point where I can drag my old bod to music stores, again. Fortunately, I haven’t worn out my welcome with local shop owners and clerks (yet).

I don’t intend to run down the DGX-670 features in detail. The Yamaha DGX-670 has been on the market for two+ years and you can find all the details on the Yamaha Web page. Yamaha position the DGX as a “portable grand piano,” part of the “P” line of digital piano products.

And, as of late, my primary interest is in a digital piano that will help me to sharpen my piano skills. I want those skills to translate to the acoustic piano (Petrof acoustic grand) at church.

In that regard, the DGX-670 does not disappoint. The action is Graded Hammer Standard (GHS) and the main piano multi-sample is Yamaha CFX. The 670 has Yamaha’s Virtual Resonance Modeling (VRM) which “reproduces the complicated interaction between both string and soundboard resonance.” The CFX sounds very good through the in-built amplification and speaker system: 2 x 6 Watt amplifier, 2 x (12cm + 5cm) speakers. If I have one immediate slam on the DGX-670, its front panel legends are difficult to read in poor light (black model).

In short, the DGX-670 has me asking, “Do I really need to move up to the Yamaha P-515 digital piano?” This question is more complicated than it sounds, especially when you roll the Yamaha CK88 into the analysis!

The DGX-670 street price is $850 USD versus $1,600 for the P-515. The store which hosted my adventure was prepared to discount the DGX-670 to $750 — that’s half of a P-515. That’s half of a Yamaha CK88, too ($1,500 MAP).

It comes down to personal musical goals — and desire. 🙂 Let’s take each alternative separately.

The P-515 has the Natural Wood X action with escapement (NWX) and the glorious Bösendorfer Imperial. That’s a lot to argue against. The P-515 sound system is more capable: 2 x (15W + 5W biamplified) amplifier, and 2 x (12cm x 6cm) woofer and 2 x 2.5cm dome. The DGX-670 has a very nice 4.3 inch (480 × 272 dots) LCD display that adds a splash of color to Yamaha’s drab black. The P-515 display has less resolution (128 x 64 dots) and is monochrome. [Yamaha should adopt the color display for the P-515 successor].

Those P-515 characteristics would be easy to live with. My biggest beef with the P-515, however, is the paucity and lower quality of its non-piano (AP or EP) sounds. The DGX-670 outstrips the P-515 for non-piano sounds. I quickly compared the DGX-670 voices against my once-beloved, owned and played PSR-S950. The DGX-670 is (roughly) a PSR-S950 without the Organ Flutes drawbar organ. I know these voices and would be very happy to have them in my piano instrument.

As to auto-accompaniment, the DGX-670 is “arranger lite.” It has styles and chord recognition. The styles are now represented in the Style File Format Guitar Edition (SFF GE) form. SFF GE makes the DGX-670 compatible with styles from the mid- and upper-end Yamaha arranger keyboards. A virtual ocean of styles are available at the PSR Tutorial web site as well as a growing community of DGX-670 players on the PSR Tutorial forum.

Yamaha do not say much about P-515 auto-accompaniment other than it’s bass plus drum, and that it follows chords. What is P-515’s chord recognition technique? Is it similar to full keyboard, A.I. recognition? Wish I knew more about this aspect of the P-515…

Regular visitors know that I test drove the Yamaha CK88, too. The CK88 is positioned in Yamaha’s stage keyboard product line. The sound system is comparable to the DGX-670: 2 x 6 Watt amplifier and 2 x (12cm x 6cm) speakers. The CK88 has the lower resolution (128×64 dots) monochrome display.

Piano-wise, the CK88 has the CFX multi-sample and GHS keybed. No VRM. No Bösendorfer. The CKs are well-equipped for drawbar and pipe organ. (The pipe organ multi-samples originated on Genos™.) The DGX-670 — and P-515, for that matter — are relatively deficient in the drawbar and pipe organ department. The CKs have a good selection of other non-piano voices. No Super Articulation. The CKs do not have auto-accompaniment of any kind.

So, if a player doesn’t care about drawbar organ and wants VRM, why not DGX-670 at half the price of a CK88?

At this point, I would be remiss to not mention slab weight:

    DGX-670 weight:  47.1 pounds (21.4kg) 
    P-515 weight:    48.5 pounds (22.0kg) 
    CK88 weight:     28.8 pounds (13.1kg)

Yamaha’s engineers did a remarkable job of slimming the CK88 down to 28.8 pounds. The respectable GHS-equipped P-125 is 26 pounds and I doubt if Yamaha can design a lighter, robust, 88-key GHS keyboard.

I neglected the whole issue of connectivity and app support. Your mileage will vary. The DGX-670 does not have 5-pin DIN MIDI. That might be a deal-breaker for some folks. Smart Pianist does not presently support CK88. Look to Yamaha Soundmondo, instead.

I didn’t work the Yamaha CP88 into the analysis. After its updates, the CP88 is a virtual library of pianos! It’s also $2,600 USD (MAP), $1,000 higher than the three digital pianos in my analysis.

Finally, why did I enjoy playing the DGX-670 GHS and not so much the CK88. Yamaha swears that the GHS action is the same everywhere. If there is an external factor, perhaps it is the insane way trial pianos are set-up in stores? Often, I feel like a contortionist. (Forget reading sheet music in some settings, too.) Playing piano is, after all, a physical act.

If you enjoyed this analysis, please check out my comments about the Yamaha P-S500. I compare the P-S500 against the DGX-670.

Yamaha Piaggero NP-15 and NP-35

Posted on by

The new Yamaha Piaggero digital pianos aren’t in the same sonic league as the Yamaha P-515, but they’re a lot easier to carry. The Yamaha Smart Pianist app supports both instruments. 

                  NP-35              NP-15

Two voices can be layered; no split. The keybed does double-duty playing notes and acting as a function button when METRONOME is held down. Hold METRONOME and DEMO together and you can adjust a whole slew of other things (tuning, transpose, audio loopback, etc.)

Yamaha Piaggero NP-15 (top) and NP-35 (bottom)

The NP-35 has a higher spec: Graded soft touch keys (vs. natural touch) and a more powerful 6W per side amplifier (vs. 2.5W per side). Yamaha describe “graded soft touch” as “heavier in the lower register and gradually lighter in touch as you go up to the higher register.”

Both instruments have the same tones: Concert Grand, Mellow Grand, Bright Grand, DX E.Piano, Stage E. Piano, Vintage E.Piano, Organ Principal, Organ Tutti, Jazz Organ, Harpsichord 8′, Harpsichord 8’+4′, Vibraphone, Strings, Strings Pad and Synth Pad.

Reverb types are Hall 1, Hall 2, Hall 3, Cathedral, Room and Stage. Chorus types are Chorus 2, Chorus 4 and Tremolo.

Both instruments do MIDI and audio over USB. If you want to do Bluetooth, you will need to buy a UD-BT01 USB to HOST Blueooth adapter. The instruments do not transfer audio over Bluetooth. (So sayeth the fine print.)

I haven’t seen prices (yet), but I would expect the new models to sell in the same range as the models they are replacing ($250 to $350 USD street).

NP-35 versus NP-32

So, what’s new?

At first glance, not too much seems to have changed. Same polyphony (64), keys are the same, simple front panel. The new speakers are slightly larger; the amplifier spec is the same.

Check under the hood and Yamaha have clearly done a lot of work. The voice offerings have gotten a significant upgrade: 3 acoustic pianos (vs. 2), 3 electric pianos (vs. 2), a new jazz organ and two new pad voices. Decent! Reverb got a small bump from four types to six. Yamaha explicitly identify the main acoustic piano as CFIIIS — perhaps an upgraded multi-sample from the earlier models?

The older models were supported by Yamaha’s Digital Piano Controller app. The new models are now part of the Smart Pianist family. That’s a big deal because NP-15/NP-35 customers are assured of updates to come.

USB connectivity is greatly enhanced. USB passes audio as well as MIDI. Yamaha are slowly upgrading their entry-level keyboards with an “USB Audio Recording/Interface” compatible with their Rec’n’Share app:

“Connect a compatible Yamaha instrument to your smart phone/tablet to simultaneously record video from your phone’s camera, stereo digital audio from your instrument and stereo backing tracks from your music library. After recording, use the app’s editing functions to trim and balance the tracks.” [Yamaha]

Unless you’re an ultra cost-sensitive customer and want to buy an older model at blow-out prices, the NP-15/NP-35 feature upgrades are worth the extra money.

Yamaha P-515: I played one

Posted on by

I’ve been toying with the idea of a digital piano at home in order to improve my meager piano skills. Too many years of organ, synths and lead sheets have let my piano skills go to seed. I want an instrument that provides a comfortable transition to the acoustic grand at the church. [After trying the P-515, I played the Petrof grand at church and the P-515 experience translates very well.]

I always like Yamaha’s top of the P-series line (P-150, P-200 and beyond). The flagship piano slabs are just portable enough (45 pound-ish), have built-in speakers, and decent action. The built-in speakers are good for practice and pass along physical vibrations as though you’re seated behind the real thing.

Yamaha P-515 digital piano

The latest model in this venerable line is the P-515. In terms of features, comparing the P-515 to the P-150 is like comparing an electronics-rich BMW to a 1990s Toyota. The P-515 communicates to the outside world through 5-pn MIDI, USB, Bluetooth, WiFi and good ole analog audio. The P-515 has MIDI and audio recording similar to a contemporary arranger. I’ve gotten a lot of mileage out of Genos quick and multi-track recording; P-515 is not too far behind. And, the Smart Pianist™ app keeps getting better and better.

Yamaha NWX (natural wood with escapement)

Then there is the keybed action. Yamaha equipped the P-515 with the NWX natural wood with escapement keybed formerly available only in the Clavinova line. The NWX is a solid step up from GHS. The only thing GHS has over NWX is lighter weight. After playing NWX, forget GHS.

The great stuff

If all you want is great acoustic piano from a $1,600 (USD) digital instrument, buy this. The P-515 has all of the acoustic sweeteners missing from Genos, Montage (MODX), CK, and even the current CP stage piano. The P-515 sound engine implements Virtual Resonance Modeling (VRM): damper resonance, string resonance, Aliquot resonance and body resonance.

Playing this piano satisfies thanks to the NWX action and excellent hand, key, ear connection. The CFX is very good and the Bösendorfer is even better. I prefer the darker sound of the Bösendorfer over the CFX, but still!

The electric pianos are not bad. The Rhodes might be a little too laid back and the Wurli might be a little too aggressive. However, you can get sweet tones out of this machine.

The not so great stuff

After picking me up with the piano sounds, Yamaha disappointed me with many of the non-piano voices. After playing Genos and MODX (Montage), I know that Yamaha can do better. Yamaha’s new stage piano series (CP and YC) have raised my expectations of secondary, non-piano voices.

Quite frankly, I find the string, pad and organ voices to be dated. The string voices are bad and not up to current standards. The dark pad seems useable in church; I cannot think of using the light pad in liturgical music.

The jazz organ sounds are long in the tooth and the pipe organ voices have been around a long time. The organ principal voice is useable. The “Phantom of the Opera” tutti is not generally useful in church. Further, Bach’s Toccata and Fugue in D Minor is not a simple piece and I wonder how many home players really use this voice? The newer CLPs have added “Grand Jeu and pipe organ flute registrations. That’s a good move and I hope they are added to the next iteration of the P-515.

Yamaha and everybody else in the home piano space needs to drop the crap choir voices. [There, I said it.] These sounds are clichéd and utterly useless. Harpsichord is on the bubble, too. There are better uses for waveform ROM.

The P-series non-piano sounds need a drastic update. Yamaha engineers need to break out of their product silos, walk over to the synth group or whoever, and ask, “Hey, what are your absolutely go-to sounds?” and adopt them. My suggestion: Cop Seattle strings, VP soft, and Genos pipe organs. Ditch a few harpsichords and add more clav or EP.

Is it hopeless?

Not entirely. The P-515 has an XG sound set. Yes, XG is dated, too, but it is comprehensive. The P-515 user interface requires a little menu-diving to find the XG sounds. The P-515 does not have a way to store your set-ups directly on the keyboard — another minus. The Smart Pianist app comes to the rescue, letting you create and store set-ups.

Yamaha, maybe add a few on-board memory storage locations in the next iteration of the flagship model? While we’re talking improvements, 1.4 Megabytes of internal memory is absurdly small, too. In this day and age, potential customers will think this a typo or a joke.

If you absolutely require a wider range of non-piano sounds, then Yamaha’s CP or YC series stage pianos may be the answer. Of course, you will spend more money.

        MAP 
Model  Price  CFX  Bösen  VRM  Keybed 
-----  -----  ---  -----  ---  -------------------------------- 
CK88   $1500   Y     N     N   GHS graded hammer 
P-515  $1600   Y     Y     Y   NWX Natural Wood escapement (X) 
CP88   $2600   Y     Y     N   NW-GH Natural Wood Graded Hammer 
YC88   $3150   Y     N     N   NW-GH3 Natural Wood Graded Hammer

The CK88’s GHS keybed is out of the NW league. The price is attractive, though, and a little bit lower than P-515, so I included the CK88 for comparison. The CP88 and YC88 lose VRM and the YC88 loses the Bösendorfer, too. The P-515 is positioned in Yamaha’s piano family (simple front panel and Smart Pianist) while the other instruments are positioned in the stage keyboard family (interactive, intuitive front panel and in-built patch memory),

You put your money down and make your choice.

Conclusion

I really want to end on an upbeat note. So, again, if all you want or need are great acoustic piano tones, buy this. With its connectivity options, I can rely on MODX or Genos for non-piano voices [at home, anyway].

As much as I want a P-515, I likely will wait for its successor. P-515 was released in 2018 and it’s due for an update. Yamaha, please?

“P” is for “piano”: Yamaha P-S500 digital piano

Posted on by

While we’re distracted with “CK”, “AN”, and whatnot, Yamaha sneaks out a new P-series digital piano in Europe: the Yamaha P-S500.

Natch, you can read all about the P-S500 at Yamaha’s European web site. Physically, it’s a minimalist slab that’s designed primarily for the home or small studio market segments. Cost is about 2,100 Euro and I would expect it to retail for about $2000 USD in the States.

Yamaha P-S500 digital piano

Basic features [courtesy of Yamaha] are:

  • Compatible with Smart Pianist app installed to a smart device
  • Stream Lights feature helps you perform even if you can’t read music notation
  • Enjoy playing along with the 403 preset Songs, covering a wide range of genres from pop music to classical music
  • Audio To Score function converts your favorite audio songs into piano accompaniment scores
  • Authentic Yamaha CFX & Bösendorfer Imperial concert grand piano Voices
  • Virtual Resonance Modeling (VRM)
  • 88-note weighted GHS keyboard
  • Huge variety of 660 high-quality instrument Voices, including Super Articulation Voices
  • Built-in Auto Accompaniment features with 370 Styles
  • Microphone input and automatic Vocal Harmony

Auto-accompaniment, styles, Super Articulation voices? We’ve seen these features in the DGX series, notably, the most recent DGX-670 model. The table below compares the P-S500 against the DGX-670. The DGX-670, by the way, goes for considerably less dough: $850 USD.

Weight          47.2 pounds       48.1 pounds

Here’s the decoder ring for Yamaha acronyms: Virtual Resonance Modeling (VRM), Graded Hammer Standard (GHS), Super Articulation (SA), Cool (velocity switched), Live (stereo), Organ Flute (drawbar organ).

The P-S500 looks to be the upscale, uptown sibling of the DGX-670. At 48 pounds, I don’t think you’ll want to schlep the P-S500 out of the house very often. In terms of styles and voices, the P-S500 is superior:

                          DGX-670  P-S500 
                          -------  ------ 
Total voices              601      660

    Sweet voices          26       27     
    Cool voices           53       47

    Pianist styles        29       13 
Drum Kits                 29       29

The P-S500 factory voice set includes many of my favorites. If you’re looking for a more than decent, mid-level keyboard with auto-accompaniment and a graded hammer keyboard, the P-S500 is worth a look. Versus a mid-level arranger keyboard, you’re still giving up a pitch bend wheel, multi-pads, style control buttons, MIDI record/edit, etc. If you just want to play and have a good piano experience, I’d go with the P-S500 in a heartbeat. (The DGX-670 is no slouch, either.)

There are many other differences that I’ve glossed over. So, if you’re trying to decide between DGX-670, an arranger or the P-S500, be sure to dig into the manuals and data list files. Yamaha doesn’t always make it easy to compare, especially as to your specific musical goals and use cases.

One enormous difference needs to be emphasized, however. The P-S500 front panel is utterly minimalist. If you want to exploit the P-S500 to its fullest, you must use the P-S500 with the Yamaha Smart Pianist app on a tablet (Apple or Android). In this respect, the P-S500 is more like the CSP series of digital pianos for the home. It’s like a CSP without the furniture. The CSP models have enhanced GH3X or NWX keybeds which improve the piano playing experience. Given that the Smart Pianist is almost a necessity, it’s kind of weird (cheap) to omit built-in Bluetooth.

Yamaha are certainly giving us choices!

A final, electronics nerd comment. While studying the internal design of current arranger, synth and digital piano products, the designs often seem like a deconstructed tablet connected to a keybed, tone generator and MIDI/USB interface. The digital electronics are remarkably similar. With the P-S500 and the CSP series, it’s like Yamaha said “Aw, the heck with it” and moved functionality out of the piano (arranger, synth) chassis into a stock, commercial tablet like iPad or Google Pixel tablet. I don’t think we have seen the end of this approach to instrument design…
